I apologize. I should have specified that when the werebeing undergoes the transformation into fullform, he/she retains full human consciousness. Some limitations:
1) The longer the werebeing stays in fullform, the more like the animal the werebeing becomes. If you changed into a wolf and remained in that form, after six hours you would begin to think and act like a wolf. The more time spent as a wolf, the harder it is to change back. If the werebeing does change back, he/she will have to stay in human form for at least the time that they spent in fullform in order for the human consciousness to reassert itself. The process is slow but gradual. Remaining in fullform or hybrid fullform for more than 24 hours willl result in the werebeing being stuck in that form, unless by very powerful outside magical influence OR (plot point) the afflicted werebeing can only turn back into human form if he/she undertakes a highly dangerous quest to the ( insert mysterious location). However, you must complete this mission in a timely fashion, for every second wasted is another part of your consciousness slipping away.
2) After a certain amount of time, say six hours, any transformation past the limbs takes a hefty toll on the werebeing's human body.
3) If the werebeing does not transform in to anything in at least three weeks, the were will fall ill. His body will be hot all over and sharp intense pains will occur periodically. As the day goes on, the illness gets worse. The feeling is akin to the feeling of an animal trying to claw it's way to out of your stomach, Which is preciscely what happened, in a sense. The beast is apart of you, to deny it would be like not feeding yourselves
However, despite theses limitations, there are some advantages.Wounds received in either form are healed when the werebeing transforms from one form to another.
